I would edit to add "Full size" semi-automatic hanguns have been used in every military conflict since WW1.
As a rule, the smaller the auto-loading pistol gets, the more likely it is to malfunction.
The wife and I were at the range a couple weeks ago and the guy next to us had a very compact .45. He couldn't get through a 6 shot clip without having either a fail to feed or a fail to eject. Every time he put in another clip full, he had to drop the magazine and clear the gun at least once. I couldn't tell what type of gun it was from where I was standing and he didn't seem in any mood to answer questions about his choice of weapon.
