Weird 2022 design, with a warning

I'm curious why SIG designed the 2022 slide lock the way they did. When you push the slide lock pin through the hole, there's a little wire on the other side that it slide against. As you push the pin through the wire slides over a little ridge on the pin, until it snaps down on the other side of it, into a little groove on the pin. This is what holds the slide lock in place.

Why did they use such a weird design? Most slide locks (e.g. the classic 1911/P238 design) have a groove on the slide lock; the edge of the slides travels through that groove, which holds the slide in place securely with no additional parts, fragile little wires, etc. Why on earth did they use this "wire" design?

That being said, here's an important heads-up for 2022 shooters. When you're installing the slide lock and pushing the pin through the hole, it's VERY easy for the end of the pin to catch the wire, instead of sliding past it. The user might not see this, because he's focused on the other side of the pistol. Then, when he applies pressure to snap the pin into place, it presses on the wire and damages it, or damages its attachment point inside the frame.

Anyway, just a heads-up to be very careful when inserting the slide lock; be sure the pin doesn't catch on the wire when you press on it, or you'll end up sending your 2022 back to SIG for repair.

Again, though... I don't understand why SIG designed it like this in the first place.

Mine has done that too. Not a huge fan of having to use a punch to reassemble my gun.

The slide stop goes in a lot easier after a few hundred rounds.

If you follow the manuals instructions for tearing it down and reassembling, it goes very easily from the very first time.

I read all the stories all over the net before I took mine apart for the first time and got worried as hell. Then I just did the step by step instructions in the manual and had no problems whatsoever.

So I'm not sure that I agree that a warning is needed. Just my opinion.

Sorry, but I guess I didn't communicate that clearly. I'm talking about the end of the pin actually pressing against the wire, NOT sliding past it and locking in place as it should. If that happens, and the user applies pressure, it can damage the wire.

Ruark, Your catch spring is not seated in the front locking block correctly. Remove the front locking block and make sure the U shaped catch spring is correctly seated in the locking block. There is a shaped recess in the locking bloc that holds the spring. If you can see the spring thru the hole, the spring wire has lost its tension or has been bent, re-bend or replace.

Just look at a 1911 it has a little plunger that goes into a tiny detent on the slide release. I have seen these fail and the the plunger tube fall off!

You're not even supposed to SEE the wire? If that's the case, yes, mine was clearly bent or broken. You could see the wire about 1/3 the way across the hole; the end of the slide lock pin would catch it and bent it out of shape.

Just got it back from SIG. They replaced the wire, and it works great now. You can BARELY see the wire on one side of the hole, and the slide lock snaps crisply into place. I put 100 rounds through it without a hitch. Wonderful. Great pistol!

When putting it back together put the side with barrel on frame and before pushing it back put the slide stop in with the lever pointing down , then pullthe slide back to the witness mark and put the slide stop back in it right place setting it all the way and releasing the slide. There is a FQ web page called Sig Pro FAQ.
