I generally stick with Glock OEM parts with a few exceptions - sights, SCDs, and Geeplates on subcompacts. With my 43 and 48 I tried two more - Tango Down Vickers magazine releases since I don’t care for the sharp front edge on the stock design, and Double Diamond extended slide stops to increase thumb leverage to compensate for an old hand injury. (I use OEM extended slide stops on my double stack Glocks for the same reason; I usually slingshot but want the ability to thumb the release without difficulty.) These two parts have proven to be trouble-free on both my 43 and 48.
One thing I always do is swap out grooved triggers for smooth. In the case of the slimlines I replace the grooved shoe with a smooth one scavenged from another OEM trigger bar.
I have a new 43X MOS coming, and I’m tempted to try a few Vickers parts. I found I had one of his slide stops for a 43 lying around, and was a little surprised that I was able to manipulate it on my 43 as well as I could the Double Diamond. Also, his replacement flat faced trigger is intriguing me - I always end up recontouring and smoothing the stock safety blade for comfort.
What are the current thoughts on Vickers Glock parts - good or bad? I’ve seen posts both pro and con in the archives, especially for the slide stops - but the problems were with the older style, not the coil spring models used on the 43, 43X, 48 and Gen5s.
