if the gun can go 200-250 MRBF, it is probably good enough to carry
I've been shooting nigh on to fifty years now. I had to google MRBF.
Is that a military term? Mean Rounds Before Failure?
Are you saying that you would carry a gun that failed every 250 rounds?
Possibly I am misinterpreting your statement, and what you mean is that 200-250 failure free rounds in a new gun are enough to prove reliability sufficiently for a carry gun. I agree, although I think 500-1000 rounds would be better. In any case, I am not trying to pick a fight. Just trying to learn.
I don't have a whole lot of experience with semi-autos. I have owned a WWII era 1911A1 for about 35 years, and have probably fired a couple of thousand rounds in that time, all factory and all hardball. No failures. My Norinco failed to fire once because I had not slapped home the magazine hard enough. It was practically new when that happened, and after everything "wore in," I have had no more problems. Incidentally, I have used cheap, gun show purchased mags in these two and never had any problems.
I owned, and carried on duty, a S&W Model 39-2 in the early 70's. I probably fired 2500 rounds through it in a couple of years. I had one stovepipe jam, for no apparent reason. Again, all factory ammo, and mostly hardball, although I fired several boxes of a couple of different hollow-point rounds. I always carried hardball on duty.
It sounds like many of you are expecting your semi-automatics to fail. I wouldn't be really shocked if the next time I shot one of my 1911s that I had a failure. I don't expect it every 200-250 rounds, though, and certainly wouldn't trust my life to a gun that failed that often.
With my S&W revolvers, I realize that a failure is theoretically going to eventually happen, but I will be surprised if it does. I have had one gun related failure in a j-frame that locked up the cylinder and called for gunsmithing. Another time, I had a factory hollow-point 125 gr bullet jump the crimp and tie up the cylinder in a Model 36. It seems like it might have been a Super-Vel round that was the culprit.
I would bet you a month's salary that you could select any center-fire S&W revolver from my safe, and that I could fire a thousand rounds of factory .38 sp +p rounds without a failure. I would be extremely surprised if I had a failure. These guns are all box-stock with no polishing or "reliability packages" or anything. My Chief's Special does have a bobbed hammer. A thousand rounds of +p would probably loosen up a j-frame a lot, but I wouldn't expect it to fail.
As you can tell, I am a revolver man, specifically S&W. I have carried my 1911s concealed, but won't any more for several reasons. Reliability is a small part of it. Ease of concealment is next, but most of all, the older I get, the more I have come to appreciate the simplicity of a double action revolver.
