+11 more
KelTec product code CP33-1333 is the factory 33-round magazine for the CP33 pistol. Its quad-stack geometry fits 33 rounds of .22 LR into a translucent polymer body, and the clear sides let the shooter inspect cartridge alignment while loading. Cutouts on both sides allow small corrections to the stack.
The CP33 magazine requires deliberate loading because each cartridge rim must sit ahead of the rim below it. KelTec's manual warns that an incorrectly stacked round can cause rim lock and a failure to feed. This magazine is CP33-specific and does not fit the PMR30, CMR30, or other rimfire pistols.
