Guns that will/won't run if they get dirty

[kd7nqb]

I have a theory that there are a lot of AK's in commie hands that have never seen a good cleaning and dont care.

As for my ownership, I dont run my M&P past 200 without cleaning it BUT that has more to do with I cant really afford to shoot a 500 rounds session if I want to see the range often. It was ingrained in me that if you shoot it you clean it, so I dont know how long it would run.

My EAA Witness 40 has gone 900 rounds without cleaning OR lubrication without failing. It ran slow as molasses by the end, but it still ran. My Buckmark bogs down after about 200 rounds if it's not oiled, but the bigger problem is that the sight base screws work loose, and the gun starts to misfire.

My Bersa Ultra-Compact 45 has been flawless, but the most ammo I ever put through it without cleaning was about 400 rounds, and it was FILTHY. It was so nasty I refused to put it back in my IWB holster! The Bersa .380 was okay after 200 rounds, but it was getting pretty gummy, and I didn't trust it anymore.

Any gun will jam if it gets dirty enough.

Not necesserally.

I tried to jam this Makarov and failed.

Anybody making a gun for the service pistol market aims at at least 250 rounds w/o cleaning. Most of the service pistol T&Es I've seen the last few yrs shoot the guns 250 rounds then cool/clean/lube before continuing w reliability/durability tests.

I have run 2K rounds through Glocks, HKs, SR9s, and M&Ps w/o cleaning and w/o any malfunctions/stoppages.

FWIW, during the XM9 testing in the early 80s, the 40 year old and many times rebuilt M1911A1s used as a reference ran better in the wet/dry mud test than the new Berettas, SIGs, S&Ws, HKs, and Walthers tested.

M1911A1, 100%/100%
Beretta 92, 97/98
SIG P226, 98/79
HK P7M13, 99/100
S&W459, 98/96
Walther P88, fail/fail

Ruger Mark IIs can go a very long time without cleaning.

Of course they have to - they're so damn hard to put back together after taking them apart....

Indeed. Here's the reason "break in" exists:

"I want to return this gun, it's not reliable."
"Shoot 500 rounds through it to break it in."
"OK."
"I shot 500 rounds through it and it still isn't reliable. I'd like to return it."
"I can't take that gun back, it's used!"
"!"
"But I do have a nice custom gunsmith you can go to that will clean those problems right up."

Right, thats why Kahr suggests a break in period in it's manual, so they can wait until 500 rounds or so have been down the pipe before they have to pay for warranty work. Makes sense.

I think break-in periods can be overstated, but there is no question that actually shooting a gun can wear it's parts in, much like you need to wear a new pair of jeans a few times before they are really comfortable.
