Wolfpack is top notch.......with mag catch modification it will run DI45 flawlessly. I'm currently working on a bolt on LRBHO for Joe (wolfpack) to add to his lower, only othe Glock lowers I recommend for DI 45 are Black Creek Precision and Angstadt. Both are also GTG for Blowback. CNC AR45 is an all time favorite as it is what got me started, but it is DI only or blowback IF you have an Olympic K45 upper.......and the Bazooka Brothers is capable of running GG mags both DI, Olympic, and colt pattern Blowback. If you want to run on a standard AR lower....My mag adapter and magazines is a pretty damn reliable option as welll
and I build DI and Blowback uppers to go with it.
Here is my personal DI AR45 on a postie lower.......Mag is 20 rounds and all steel construction......and can be installed in under 60 seconds.
As far as the original question,..
...I have a bunch of SGM and had zero issue with them.
