Full slide disassembly? YES!

[Tinman507]

First time I pulled the slide apart on the CM9 I swore a storm & even invented a few new words. I finally bought a cheapie set of jewelers screwdrivers at Lowes.

The little teeny one is the ticket. Pushes that extractor pin down. It takes a lot more force than you originally think it should. Once you feel it move it's a piece of cake. The other essential tool is the Ripley's Wire Hanger clamp. Holds the Striker pin back without a 3rd hand. Here is where a good stout gallon freezer bag is essential. You most definitely do not want all those tiny pins springs and parts launching.

The whole procedure is enough of a PITA to do the Brake Cleaner spritz for most maintenance, but for complete peace of mind, I am doing at least an annual full strip down. I figure also that I will replace the striker spring at that time. A 3 pack from Wolffs is cheap enough.

I appreciate engineering masterpieces and the innards of this slide fit that description. Learn how the gun works and become intimate with it.

I hadn't done one on my PM9 in about 500 rounds, so I decided to do a full strip. Below is a picture of brass flakes I found in the striker channel. Shown below are three Q-tips. It took an additional three Q-tips before I got all the flakes out.
I use mainly WB FMJ.

On the basis of my finding, I plan to do a full strip AT LEAST every 500 rounds.

J, I was just wondering if you ever clean the striker channel with non-chlorinated brake cleaner after every range session? By doing so, I believe that you could avoid doing the full strip of the upper more than once a year.

Seemed like it was on there with Gorilla glue. Seriously. I even called the gunsmith I used for my night sight installation and asked him if it was as difficult for him as it was for me. He agreed it was and joked he should have charged me more.

If you're forced to use profanity when disassembling a Kahr upper you are doing something wrong.

I don't see how blowing anything through the blow hole, including break cleaner, can get rid of brass flakes without opening the striker channel. The little blow out hole will just push the flakes around inside the channel since there's no place for the flakes to exit the channel.

For the record, I use only Ballistol to clean and very small amounts of M-Pro 7 to lube.

how do you get it into that little hole?

I also pull the striker to the rear and blow the NCBC through the striker pin hole to force stuff out the back... at least out of that front area where it could build up and slow or stop the striker from going forward all the way.
