In the full size original model torn apart here, the safety doubles as the sear pin and this moves the pivot to a poor position. The Compact model remedies the biggest complaint I have with the M&P22 – the thumb safety. 22 that feeds a huge variety of ammo but ultimately doesn’t feel like its centerfire big brothers where it counts. Some parts of the design seem to be drawn from other S&W rimfires like the 22A and 41, while a few elements are drawn from the centerfire M&P itself. 22 look-alike that follows the trend of abandoning the striker fire mechanism in favor of a conventional single action only internal hammer. Drive the frame roll pins in and center them up. Press the whole assembly down against the hammer spring, making sure the hammer strut is engaging it properly. Drop the hammer spring and cup into the hole in the plastic grip frame, then ensure the hammer is FORWARD before proceeding.
If you insist on putting the mag disconnector back in, you can install it now.Both of these fall into place, the sear spring has a little hole for a seat on the sear. Pull the tail of the trigger bar out slightly and slot the disconnector peg over it. Pushing the trigger pin part way from the outside (right side) will help keep it in place while you snag the trigger spring with a hook and wrestle it into position.
It takes some wiggling and trial and error to get the slide stop over the receiver plate, and it’s best to squish the slide stop spring and prod it into place with a punch or hook then rotate the trigger assembly into place. Working backwards from where we left off removing the trigger assembly…
These two identical pins retain the actual serial numbered frame into the plastic grip shell, and the hammer spring pushes upward making your job a little more annoying.Ī dental pick, geometry and patience are needed to get this apart and back together. Rotate it 90 degrees clockwise and it will wiggle out. Align the firing pin block and start the roll pin from that side to make it easier to keep it in position. There’s a little hole in the slide for it, so if it’s misaligned it won’t depress fully. Once the extractor is in and spring loaded properly, insert the whole group and slide it to the rear as far as it’ll go. Leaving the front of the unit tilted “upward” (we’re working with the belly of the slide facing up as pictured) will give the extractor just enough space to push the plunger aside and snap into place. You can’t keep the extractor parts in place, so drop the spring and plunger in and align the assembly with the cuts in the slide.
Drop the firing pin spring in the slot on the top, drop the firing pin in after it and push it into place where it’ll stay put for now. This guide also covers removing the magazine disconnector “safety” which can be omitted with no negative effects on the gun’s function and no parts or spacers are needed.Īll of the parts of the breech face assembly. I recently had the opportunity to compare the newer Compact model alongside the full size example that I’ll be ripping apart in this guide, so I’ve included a few notes along the way to highlight design changes on the newer pistol. It took Smith & Wesson a few years to catch up, but they appear to have spent their time wisely and learned from the failings of other guns to make the M&P22 a reliable little package. 22 lookalike pistol that hit the market seemed plagued with issues, the Walther P22 and Sig Mosquito were at one time famously problematic as they fought through their growing pains. It seemed like the next logical step up from expensive conversion kits that nearly cost as much as a standalone rimfire pistol by themselves and were often difficult to find in stock.
22 as a training tool exploded a few years back just before the great ammo drought, ushering in a golden age of rimfire lookalikes mimicking popular defense handguns.
