I am sure I once read that Jeff Davis Milton, one of the all time great lawmen, got rid of his 38/40 because it would set back and jam the cylinder.
I have heard of other people having the same problem. I have never fired one myself.
The 10mm is a nice round. Unfortunately it's dying out there. Other than the Glock you can't really buy a gun that is chambered for it. Smith discontinued all their pistols (but have one revolver for it). Colt doesn't make the Delta anymore. Kimber and Springfield don't chamber for it either. Sig - Nope. CZ - Czilch. HK - Hardly. Ruger - Nada. Supposedly there is an Italian one but they are scarce. (Tanfaglio imported by EAA) you can get but I had one on order for six months and my shop couldn't find one)
So it might be a great round, but your gun choices are limited. You can buy a Kimber .40 and send it to a high end smith and get a conversion.
Given that I bought another .45. Yeah, I like the ten but it's like handloading wildcats... just too weird for the additional spunk the round has.
If it revives and more guns get chambered and more ammo makers start making ammo I'd consider getting one...
