The Smith & Wesson striker-fired lineup splits into two distinct aftermarket ecosystems. The Shield Plus is a micro-compact 13+1 carry gun on the Shield frame with the Shield RMSc optic cut. The M&P 2.0 Compact and M&P 2.0 5" Full-Size are duty-size pistols on the M&P frame with the RMR optic cut. Apex Tactical dominates triggers for both, but the specific kits are not cross-compatible, and the optic footprints do not overlap. This guide ranks the best upgrades and accessories for all three models side-by-side, with every pick tagged to the specific variants it fits.
Not every M&P upgrade delivers equal value. Start with the change that most transforms how the pistol shoots, then work down the list as budget allows.
Weapon light, red dot, spare mag, and trigger, the upgrades most pistol owners add first.

The M&P 2.0 Compact OR and M&P 2.0 5" OR Performance Center slides use the S&W C.O.R.E. / optic-interface plate system for RMR-footprint optics, the same optic class as the Glock 17 MOS, Glock 19 MOS, and SIG P320 X-Series. Use the correct S&W factory plate or an aftermarket steel/aluminum plate for the optic footprint; it is not a direct RMR slide cut. For the deeper comparison across every pistol optic, see our best pistol red dots guide.
Best Overall - Multi-reticle RMR-footprint optic with solar failsafe
Best Carry Reliability - Enclosed emitter for full-size M&P 2.0 duty or EDC
Best Premium - Forged housing and the widest mount ecosystem

The Shield Plus Performance Center OR uses the Shield RMSc footprint. This is the compact micro-optic cut shared with the SIG P365 XL, Glock 43X MOS, and Springfield Hellcat OSP. Holosun K/RMSc direct fit depends on the exact slide cut and recoil-lug pattern; RMRcc requires its own adapter plate. For daily concealed carry, the enclosed-emitter picks are preferred because pocket lint and sweat cannot block the dot.
Best Overall - Enclosed-emitter reliability for Shield Plus carry
Best Value - Proven multi-reticle optic at the lowest price in the footprint
Best Premium - Trijicon durability in a compact footprint

Apex Tactical is the dominant aftermarket name in M&P triggers and functionally owns the segment. The Forward Set Sear and Trigger (FSS) kit is the gold standard for the M&P 2.0 line and comes in polymer ($110) and aluminum ($180) shoe versions. The Shield Plus uses a different frame and sear geometry, so Apex sells a separate Action Enhancement Trigger & Duty/Carry kit that covers the original Shield, Shield 2.0, and Shield Plus under a single SKU. None of the three kits are cross-compatible, always confirm your pistol model before ordering. For the broader AR-pattern trigger discussion (which follows different rules from pistol triggers), see our AR trigger guide.
Best M&P 2.0 Trigger - Drops pull weight, shortens travel, resets crisper
Best Premium - Aluminum shoe and anodized finish on the same FSS platform
Best Shield Plus Trigger - Duty-carry tuned, maintains factory safeties

The factory M&P steel three-dot sights are acceptable but thick. A narrow tritium front post improves front-sight precision at 15+ yards, and tritium rear vials add low-light visibility without forcing a photoluminescent front outline. The Trijicon HD XR is the premium pick and drops into the M&P 9/40 and M&P 2.0 dovetails without gunsmithing. If you are also running an RMR or Shield RMSc red dot, search for the suppressor-height version of the same sight set so the irons co-witness through the optic.

This section applies to the M&P 2.0 Compact and M&P 2.0 5" only. The Shield Plus has no accessory rail and will not mount a weapon light. The M&P 2.0 Picatinny rail accepts every compact-class pistol light on the market, but the TLR-7 family is the de facto default because it has the widest holster support. The Compact takes the standard TLR-7A cleanly; the 5" has room for the higher-output HL-X variant. For the full field of options including SureFire and Modlite, see our best pistol lights guide.
Best Overall - Fits both M&P 2.0 Compact and M&P 2.0 5" without overhang
Best Output - 1,000+ lumens for M&P 2.0 5" home defense duty

The M&P family has some of the broadest holster support in the industry. Every major Kydex maker molds dedicated shells for at least the Shield Plus and M&P 2.0 Compact; most now include the M&P 2.0 5" as well. The picks below cover four carry configurations: minimalist AIWB, budget-friendly broad coverage, all-day hybrid comfort, and a full sidecar rig with an integrated mag carrier. For the wider field of IWB, OWB, and hybrid designs, see our best concealed carry holsters guide and the matching CCW gun belt guide.
Best AIWB - Deep appendix concealment across the full M&P lineup
Best Value - Broad M&P coverage with optic cuts included
Best Comfort - Leather back distributes weight for all-day carry
Best Full Rig - Complete AIWB system with integrated mag carrier

The Shield Plus and the M&P 2.0 are built on different frames and use different optic cuts. Most upgrades do not cross over. Use this table to confirm a part fits your specific model before checkout.
| Upgrade | Shield Plus | M&P 2.0 Compact | M&P 2.0 5" |
|---|---|---|---|
| Optic Footprint | Shield RMSc (PC OR) | RMR (OR model) | RMR (OR model) |
| Apex FSS Kits | Not compatible | Yes (polymer or aluminum) | Yes (polymer or aluminum) |
| Apex Shield Kit | Yes | Not compatible | Not compatible |
| Iron Sights | Shield dovetails | M&P 9/40 dovetails | M&P 9/40 dovetails |
| Weapon Light Rail | None | Picatinny | Picatinny |
| Magazines | Shield Plus only | M&P 2.0 Compact | M&P 2.0 Full-Size |
| Holster Shell | Shield Plus mold | M&P 2.0 Compact mold | M&P 2.0 5" mold |
Key takeaway: Apex sells different kits for the Shield family and the M&P 2.0 line, never cross-order. Red dot footprints do not overlap either: Shield Plus PC OR takes micro RMSc/K-class optics, M&P 2.0 OR takes RMR-class optics through plates. Iron sights, holsters, and magazines are all model-specific. For how the M&P 2.0 stacks up against full-size competitors, see our best full-size 9mm pistols guide. For the Shield Plus in the micro-compact class, see best subcompact 9mm pistols and best CCW pistols.

Use our pistol builder to sanity-check a complete M&P 2.0 build against your budget before committing to every upgrade at once.
The Shield Plus ships with two magazines, which is the minimum for function and not enough for any training use case. A defensive shooting class burns 8 to 12 mags an hour. A serious carry rotation needs 3 mags at minimum so you can keep one loaded for carry, one as a staged spare, and one rotating for spring health. The Shield Plus is a primary carry gun for most of its owners, which means the magazine rotation matters more here than on a range-only pistol. Do not load the same mag to full compression for months without cycling it.
Minimum mag count by use: EDC carry: 3 (one in the gun, one on-body, one rotating). Range and training: 6 to 8, enough to run two-mag drills and reload practice without stopping the timer. The 13-round extended is the primary EDC mag for most Shield Plus carriers; the 10-round flush is for deep concealment in situations where the shorter grip profile is needed.
Variant compatibility: Shield Plus magazines are specific to the Shield Plus and do NOT fit the original M&P Shield or Shield 2.0. The 10-round flush and 13-round extended are the two standard Shield Plus mags. The 15-round extended is available for the Shield Plus 4-inch Performance Center variant. The M&P 2.0 Compact and Full-Size use completely separate magazine bodies; none cross-fit the Shield Plus frame. Always confirm the SKU is labeled for the Shield Plus, not just the Shield family.
