Griffin Armament Revolution 45

The Griffin Armament Revolution 45 is the budget entry for a 10mm shooter, and the cheapest modular .45-bore can in this list. Griffin rates it for pistol and subsonic calibers with projectiles .458 and lesser diameter, which is a maximum-diameter rating rather than an enumerated caliber list; 10mm's .400-inch bullet sits well inside that limit, so it is a covered, rated use rather than an off-label one. It runs 17-4 H900 stainless baffles in a 7075-T6 aluminum tube, keeping cost down while staying full-auto rated on subsonic and pistol loads.

It is modular between a 6.56-inch short and 8.81-inch full length and ships with a booster assembly and Griffin's universal EZ-LOK piston. Budget for the adapter: Griffin states plainly that EZ-LOK barrel adapters are required to use the EZ-LOK system and must be purchased separately, so a tilting-barrel Glock 20/29 or 10mm 1911 needs the matching barrel adapter on top of the can. It gives up a little weight advantage to the titanium cans at 13.3 ounces full, but at street prices near $650 it is the value play for a shooter who wants a rated 10mm can without a four-figure spend.
