I've referenced material from 10-8 before, and read/forward their articles to many, so I might was well do it here as well.
If you own a 1911 you owe it to yourself to check out this stellar reference site: 10-8 Articles, also of interest is their blog. I recently picked up one of their Armorers blocks and it's proved useful in the short time I've had it. Just the other day their Gen 2 Slide Stops were back in stock and I decided to get one as my Nighthawk was not consistently locking open on empty with Wilson ETMs, so far it seems to work as advertised, the pad is nicely oversized without being overly large. I also picked up some 10-8 Lube and some Armorers Tools. We'll see how this slide stop performs now that IDPA is getting to start back up as well as some scheduled training this Spring. The wife and I are heading back to TDI for Pistols II & III to fill the prerequisites for Team Tactics.
I totally spaced during my ordering process as I meant to get some of their nifty slotted screws designed to work with a .45ACP casing, oh well, there's always next time. If the slide stop works well for me I'll probably order another for my Springfield.
