I'm not going to say "don't but a Serpa" but I will say that you should Google Serpa ban and continue your research and try to be more informed about your holster purchases.
I will say that you could not give me one to wear, especially if I were a novice shooter looking so start in the gun games.
Blackhawk can make a good holster, is look at thier CQC holster which lacks the button. Most I've seen in competition that are usinng a Serpa have disabled the locking mechanism.
Blackhawk Sportster Standard CQC Holster
Item #: 415600BK
Got the blackhawk CQC holster, 5 mags for the 92FS and a pair of double stack mag holders. Now about the belt. I saw a "duty belt" setup that was a 1 1/2 inch inner belt that goes through the belt loops of the levis and a second belt about 2 inches wide that is much stiffer with a snap closure that I attach the holsters to. Both have velcro to hold on to each other and the theory, I guess, is to place the weight on the 2 inch belt cinched over the hips rather than pulling my pants down. Also when I need to disarm all I need do is remove the larger outer belt. Guy at the army/navy store called it a "duty" belt rather than the other one next to it that was a little less stiff labled a riggers belt. This sound like what I am looking for? Total cost is about $25 - $30 for inner and outer. Weather is turning warmer and it might not snow next weekend, I want to be ready. Looking to take a class with a local USPSA instructor on the basics as well. Still need ammo though.
Thanks all for your input.
Sounds like you're good to go. Just make sure that the holster will fit the outer belt.
Now--your first match: 1) Do not expect to be competitive. Dont think you're going to walk in and give the local GM a run for his money--you're not. You'll be worried about looking bad, and you will look bad. Dont worry about that, worry about looking safe. The first match is kind of a throw away. You likely wont remember your runs (no kidding), you almost certainly will not be able to call your shots, and you may not recall a single sight picture. This is normal. Your second match, take notes on what you want to work on, specifically. No "EVERYTHING" remarks, actually list them. Then get with other shooters and ask them how to do that.
2) Go help setup and tear down the match. This will make the other shooters more inclined to help you and give you a nice advanced look at the stages. They will be short on people who are willing to help and you will be viewed as a godsend.
Have fun man! You are sticking your toe into some very deep water. I'll be here if you need some help further down the line.
