This model is not for the frame integrated A1 version, it will not work.
The danger of serpa... I find it not the case
1) I crawl/roll on the ground with holster at my thigh through snow, didn't jam when I needed it.
2) I can't see the ND occur if you draw by sliding your index finger through the release
Overall I'm happy, definitely a good buy!
Pros: Affordable, high quality, durable, functional
Cons: Does not work with M9A1/ Beretta 92A1
