I have a legacy DA|SA 22lr P226, and a DAK 40 caliber P226. When I use both frames for 9mm the 22LR DA|SA frame locks open on an empty 9nn mag 100% of the time. The 40 Caliber DAK frame only locks open on a 9mm magazine about 15% of the time. When I took a deep look into this, I noticed that the slide lock lever on the DAK frame has a smaller tab that doesn't extend into the magazine well as far as the tab does on the 22lr DA|SA frame. When I did a search for parts compatibility I found this info:

"Anyone converting a Sig Sauer P226, originally made in .40 S&W, may find themselves in a frenzy, with converting it to 9mm, even with a Caliber X-Change kit. Sig used a Slide Catch Lever that currently is known a Lever-1, which was made for .40 S&W only, in the P226."

I see P226 slide stop levers labeled as Lever-2 part #1200628. Is this the lever I need to convert my 40 caliber frame to work with 9mm magazines? Thanks for any info.

If you look at your .40 magazines, you'll probably notice a small bump out to the left on the follower. When I bought a 9mm conversion barrel for my .40 DAK, I could not get the slide to lock on the 9mm mags because they didn't have this bump. I called Sig and they sent a new slide release lever that works with both calibers' magazines.

I can't verify the part number, but that was the only part I've changed. IIRC, it also fixed a problem I was having with the different ogives of the two rounds contacting the lever.
