Jimbob_tx, you said:
I still don't see a ringing endorsement FOR the Serpa. I see defense of it in this thread, but what problem is it designed to solve, outside of gun retention?
Stop there.... gun retention is exactly what the SERPA addresses and is important.... Thinking that gun retention isn't important is living in
movie world where gunfights are clean, planned things that happen in a vacuum.
The rest of your post is missing a huge point that is also important for you (and anyone) to understand: The SERPA
does support trigger finger discipline and proper placement.

Be careful about over thinking the problem or starting from an assumption that there is a problem that doesn't really exist... that is the reason I brought up Kabooms! in the first place......

I don't want to pick on you, but:
I've said before that I don't have any personal experience with the system
.... that's
kinda relevant here..... you are working on assumptions that are
really flawed.
Anecdotal "evidence" and "erring on the side of caution" is what leads to no one being able to shoot from the holster on public ranges.... or shoot more than one shot per second.... or have CCW permits...... or own guns at all...... etc, etc.....
5 years ago, this was the discussion over whether or not it was "OKAY" to let people take defensive shooting courses with IWB holsters. Seriously, there were schools that didn't allow it because the instructors thought is wasn't safe.... or were afraid of the liability.... or couldn't figure out how to teach their use safely because it wasn't what THEY used. The same is true on some ranges where people aren't allowed to use shoulder holster, crossdraw, fanny packs or ANY other method of carry. If the instructor can't figure out how to help a student become better prepared to use their method of carry, they shouldn't indite the method out of hand. FWIW, if an instructor has the integrity to say " I don't like it, so you can't use it!" OR "I don't know how you can use it safely, so you can't use it" I have
nothing but RESPECT. At that point it is up to the student to make a decision about the instructor's opinion.....
If I have student show up who is carrying a 1911 and insists that holster-less pocket carry, chamber loaded with the safety off is his preferred method..... well, in that case, I think I can make a 98+% safe statement that "no reasonable instructor" would allow it. Either way, I am okay with the student making a decision about my opinion and choosing where to spend his money and time. The SERPA issue is a far cry from that type of situation.
