Seems to be.
I formed it over an 1/8" parallel. I put the retainer on it thinking that if the gun was tight it would help the holster stay in my waistband without pulling it out with the gun. Thats a problem that I've had with some clipped IWB holsters that I never was fond of.
The clip is a part of the original sheet. I rough cut the holster and then formed it to the gun. Once I got a satisfactory fit, I riveted it. Then I trimmed it up some and then formed the clip.Although the clip has an 1/8" gap to accomodate a leather belt, the end of it actually touchs the holster when its out. This sort of gives it a bit of "spring" tension. Its actually tight enough that it may not have needed the retainer, but I figured it'd be better safe than sorry.
A press would have been nice. As it was, I just used my hands, with leather gloves of course. Even with the gloves on, it was a bit warm. The thing is, you dont really need a press, I just kept pressing with my fingers over the gun, so anyone could do it as really the only thing needed is a heat source and a way to cut it and and a drill for the holes.
You ought to try it. A man of your talent will have no problems.
