I guess it didnt like some spray cleaner that I used because it immediately lost its tension/shape and snapped with the first cycle of the slide. I've ordered a few from HKP but is there any reason I cant use this thing until they arrive?

Use it, it will be fine and won't hurt anything. Didn't you get extras with the firearm?

 

[IDontHaveTheTrunkSpace]

It was some Hoppe's 'barrel blaster' spray, in a can, the type that comes out really cold and dries fast, almost like keyboard duster spray with a solvent added. Maybe the cold temperature did it? Maybe it was just a coincidence who knows. I dont recall there being extras in the case it came with but I dont know....its not with me at the moment anyway. Ive got a few on order, thanks for the info though guys

Here's a post about the lack of o-ring... http://www.hkpro.com/forum/hk-handgun-talk/143338-hk45-win-range-again-2.html#post1061180

O-rings don't like temp changes, take it off next time I can send u a spare to get by with if u want

What color o-ring? That should never have happened to a green one. :wink:

Just take that thing off before you clean, and reinstall after lube.

I haven't had any problems with my o-rings, while shooting or cleaning and was wondering how often they should be replaced.

...was wondering how often they should be replaced.

When they are broken.

What is the purpose of the O-ring on the barrel?

+1. Well said , only green on my machines

What is the purpose of the O-ring on the barrel?

There's a slight amount of clearance between the barrel and the slide - necessary to allow the breech to unlock as the action cycles. The o-ring takes up that clearance and makes for a slightly more consistent alignment between the barrel and the sight plane of the slide.

In practice it's been found to make only a slight improvement in accuracy because the tolerances are quite tight to begin with, but it's a step in a right direction for greater accuracy - no matter how slight.

Thank you for the answer, apologies for taking post off topic.
