I have to agree with our friend Rob Pincus.  Rob is one of the most active trainers in the Gun World.  He’s always on a range.  And he’s describing exactly what I’ve been seeing as well.

I’ve only had and seen good results with small 1911’s from two sources.  SIG and Detonics.  None of the others have run properly.  I don’t know exactly why that is as I am not a Mechanical Engineer. I’m a Low Brow Knuckle Dragging Gunslinger… I know what works and what doesn’t. I’ve seen more failure to function with 1911’s than any other handgun type. In fact, I’ve only seen one 1911 run through a course without a failure. That was an STI in 9mm run by our friend Larry Correia. His “Cheater Heater”. Anyways, back to the caution on these Ultra Compacts. Be careful with them. Find loads that run in your pistol. Lubricate them with Slipstream Weapon Lubricant. Find how many rounds you can go through before the gun starts acting up and needs to be cleaned again. If your gun is not reliable – then for the love of all that is good in the world… Don’t use it for defense. Just Don’t. To do so would be to make a Jump with a Chute packed by the kid that takes out the trash at Wendy’s. Not Bright. If you have an Ultra and you like it… and it isn’t quite reliable. Have a Gunsmith go through it and tune it up.
