Smith & Wesson 18+1 High Capacity Magazine Modification

Everyone wants more rounds in the gun. I've always been a believer of more bullets and after shooting many years of competitive pistol shooting where one extra round can mean the difference of 1st or 2nd place... it stuck with me. In competitive shooting like IPSC and USPSA, there are many companies that make basepads for added capacity for center-fire handguns like the 9mm, 38 Super, 40S&W and 45ACP. But no one really seems to care about the 22. For years I have been a big fan of the 22LR. I've even been accused of having a fetish of sort and to be honest, I couldn't tell you how many 22's I've owned over the years. So for those of us looking for more rounds in our 22's, you can find a potential answer to your quest at our website Taylor-Tactical-Supply

But here in particular I wanted to give you a close up look at the 18+1 MAGAZINE UPGRADE KIT for the Smith & Wesson M&P22 pistol. This kit replaces the internal parts of the factory magazine regardless if it's a 10 or 12 round mag. The kit is comprised of a new Hi-Viz follower, extra power magazine spring, aluminum basepad and hex wrench. You can find them HERE



The kit installs in minutes and is reversible if you want to ever convert your magazines back to original configuration. Simply dismantle your factory magazine and bag up everything for storage but the magazine tube. Insert the NicTaylor follower into the magazine tube and then the extra power magazine spring taking note of the orientation of the spring. Compress the spring inside the magazine tube and slide on the anodized aluminum basepad. If for some reason the basepad does not slide on, it may be necessary to remove some of the metal on the little wings of the magazine tube. The magazine tube is stamped and formed sheet metal and the tolerances can vary from mag to mag. Make sure that the spring fits into the inside pocket of the basepad and use the included hex wrench to finger tighten the set screw on the bottom of the basepad.





Draw backs on a kit like this is that it may not be legal in your area. Lots of states and municipalities do not allow magazines over a certain capacity. So make sure you know your areas laws before you install a magazine upgrade. Also we recommend using high velocity ammo for this kit. With so many rounds in the magazine, there is more pressure exerted on the bottom of the slide. This pressure is difficult to overcome as the slide attempts to cycle with the use of some low power ammo. Even with high velocity ammo, the slide may not lock back every time on the last shot fired.

If you live in an area where 15 rounds is the limit for a magazine then you are still in luck. You can get the original 15+1 magazine upgrade HERE And for those that do not have the full sized version of the M&P22, but rather have the COMPACT, you can get a 14+1 magazine upgrade HERE
