1. Semi-automatics are sensitive to bullet style and weight.
Yea, maybe. Then again, maybe not.
Then again, some revolvers are sensitive in the same respect. The S&W model 19 as an example.
2. Semi-automatic ammunition is restricted much more limited power range for reliable functioning than revolvers.
I dont agree here. I routinely shoot +P+ 9mm out of my Glocks, and have never had any function issues because of it.
It would be interesting to see a little test, of two random, current, and realistic guns (i.e., normal carry examples) , one auto, one revolver, and shoot caliber extreme ammo (+P+, etc) until one fails. Which do you think will prevail?
I have a pretty good idea as to the answer. I have a Glock 17 that as of 9.5.15, has 88,000 rounds through it, without any stoppages that werent ammo related failures, or intentionally set up stoppages. No parts have yet broken.
Ive replaced RSA's twice a year, and have replaced extractors twice, although, it seems now, neither were in fact an issue, and it was worn out brass that was the issue. I actually replaced the second with the one it replaced, and its been fine. I tossed the original, so I couldnt prove it for sure.
Ive had a number of revolvers that didnt hold up for the first 1000 rounds.
3. Semi-automatics are more sensitive to improper shooting techniques such as improper grip.
Meh. Again, maybe. Then again, if youre shooting revolvers with the same improper techniques/grips, even if the gun does continue to work, youre not likely going to be hitting anything with any regularity, if at all.
I shoot a lot more auto than I do revolver, and I shoot a fair amount of revolver each year. Usually 5000+ rounds anyway. I shoot at least 6 times that out of my autos.
Over the years, Ive had more malfunctions with revolvers than I have the autos, and 99% of the revolver malfunctions, were DRT malfunctions. The gun was out of action at that point.
99% of the auto malfunctions are fixed almost immediately, with a TRB.
About the only plus I can see with a revolver, "might" be shooting through a pocket, but even then, its not a guarantee that it will work with all revolvers, nor is it a guarantee that it will fail, with all autos, so its basically a draw.
Pretty much everything else revolvers are supposed to be better at, are a reach at best.
