Cleaning the ISSC M-22

I got my wife an ISSC M-22 for her birthday. It is a really great gun and loads of fun (and cheap) to shoot. I took her to the range yesterday and we ran 100 rounds of CCI Mini Mags thru it. VERY accurate and very functional. I was, however, a bit perplexed about the best way to clean and lube it so I had written ISSC about my concern and when we got back from the range, there was a letter from the Director of Training. What great customer service!! With his permission, here are his suggestions for cleaning the M-22:

Dear Bob, <o:p></o:p>
<o:p></o:p>
I don't clean my M22s until they stop running reliably. Usually after about 300 to 500 rounds depending on the ammunition and how well the gun has been broken in. (This generally means how many rounds have been through the gun.) Here is how I clean my M22 pistols. <o:p></o:p>
The first thing I do after removing the top end is remove the spring and wipe down the barrel. Next I prepare the inside of the barrel for cleaning. The grip frame and barrel, the lower end), are all one piece. I use one of the foam cleaners. Holding the gun so that the barrel is vertical, muzzle up, I shoot the foam into the barrel from the muzzle end until it starts to come out the chamber end. Next, I prop the lower end up against something so that the barrel is completely vertical, muzzle down. The idea is to prevent runoff into the action below. I let it sit in this position while I am working on the slide area. The foam will turn into a liquid and drain out the muzzle end. <o:p></o:p>
<o:p></o:p>
To clean the top end I use a Q-tip to run inside the rails. This is the channel found on both sides at the bottom inner portion of the slide. If they are particularly dirty I will soak the Q-tip with Gun Scrub or an automotive Brake Cleaner and run it through the channel again. But, I never use the spray directly on the gun to flush out dirt. I also wipe out the inner surfaces of the slide. Once clean I put a drop of oil at 4 different points. These points are inside the frame rails. Two points opposite each other about 1/2 inch from the rear of the slide and about 1 inch from the front of the slide. Then I put the slide down on the bench upside down as I work on the top end. <o:p></o:p>
<o:p></o:p>
Continuing with the top end I pick it up and hold it so that the barrel is vertical muzzle down. I wipe away the solvent from the chamber ramp and the areas surrounding it. I use a brass rod with a .22 cal brush through the barrel from the chamber side. Push all the way through and pull all the way out. If you are using a nylon bristled brush it is safe to use a scrubbing action inside the chamber area, (the rearward length of the barrel that holds the round). But, don't scrub so hard or unevenly so that the wire that supports the bristles contacts the bore. <o:p></o:p>
<o:p></o:p>
To stop the solvent action from eating anything but the debris inside the barrel use the Gun Scrub or break cleaner. Attach the thin guide tube to the nozzle and push the tip into the chamber. This is the only time it is recommended to spray the gun. The cleaner should dry quickly but you can push through a dry patch to make sure. Check for debris sticking to the flat area around the chamber mouth. The edge of a piece of hard plastic is the best way to scrape away dirt and lead that can stick here. <o:p></o:p>
<o:p></o:p>
Next, take a look at the hole where the firing pin shoots through the breech face. A plastic or metal pick can be used to pull out unburned powder if necessary. Take a look at the breech face itself. Surrounding the firing pin hole the surface is contoured to hold the rim of the cartridge. Use the metal or plastic pick to to clean the groove by running it around its edges. A nylon brush can also be helpful here. <o:p></o:p>
<o:p></o:p>
Now I return to the top end and use a Q-tip to clear the frame rails just like I did the rails inside the slide. Before reassembly you may want to run a patch with a small drop of oil through the bore. This is recommended for any firearm that is going to be stored for a period of time. <o:p></o:p>
<o:p></o:p>
After reassembly we recommend a drop of oil at the front edge of the barrel hood where it contacts the edge of the ejection port. <o:p></o:p>
Also, pull back the slide and lock it open. Apply drop of oil to the outer surface of the barrel. <o:p></o:p>
<o:p></o:p>
I have to tell you, Bob, writing it down was more work than doing it. I know it was not nearly as pleasant. I find cleaning guns to be very relaxing. It is also a good way to bond with the weapon. Please feel free to contact us again if you have any questions. Thanks for writing. <o:p></o:p>
