Hi Standard 22 Pistol - Model 103

chemeng

Just purchased the Model 103 over lunch today. Got a great deal on it, can't wait to try it out.
Does anyone know how the barrel takedown works? It has what appears to be a push button just above the front of the trigger guard. I tried pushing it but it does not work. Do you have to remove one of the pins or am I just overlooking something? I would like to fully disassemble it to give it a good cleaning.

Thanks in advance, Mike

Insert an empty magazine before attempting this.
What you do to disassemble it is hold the barrel of the gun(after being sure it is empty) with your weaker hand with the thumb side of this hand facing toward the trigger guard. Then, you crook the index finger of your stronger hand thru the trigger guard and put the thumb of the stronger finger on the button. Using the leverage of the index finger, you push the button and lift off the barrel with your weak hand.

The button disengages a release on the frame which in turn releases a stud on the barrel, allowing the barrel to come free. Its a little tricky the first few times you do it but after the first time you do it, you know exactly how to do it from then on.
On older HS's that have sat around for a while, disengaging the barrel
can take a little effort. My trick to "unfreeze" the joint is to tap the button LIGHTLY with a rubber or plastic mallet. This will often unfreeze the connection, allowing the above process to work a little easier.

That did it! Gave it a tap with a small block of wood and it loosened up. It hasn't been disassembled in awhile, the cleaning will do it good.

Thanks again, Mike

Should you decide to remove the right grip, be very careful to keep the slide stop in position, as the coil spring in the front of the slide stop has a way of becoming airborne if you don't carefully remove the slide stop. There is also a bent whisker spring under the plate on the left side which also can become airborne during disassembly. There is spring kit available from WOLFF company -- stock # 69191. You might want to pick up a couple of these kits.

Another warning - only shoot SV ammo in that gun. Slide cracks are common in them - usually on the right side - from shooting HV ammo.

Brownells has a lot of parts for them. These guns can have feeding problems, the HS (Houston) website has good instructions for adjusting the magazines to fix feeding problems.

chemengThanks for asking the question.rick_renoThanks for the lesson.I saw this post and just had to look. After reading it I reached over (without getting out of my chair, it's that close.) and grabbed the old 103, did what rick said and yes with a slight whack with the 10 pound sledge (well maybe it was not quite that big) it did come right off. I never knew how and I did not think to ask.You never know what you will learn reading this board.So thanks again to both of you.

If I knew then, what I know now.

Just got back from the range. I had a few minor feeding problems, on closer inspection the clip has been repaired. The baseplate has been reattached with two brads and blued over. It has altered the feed angle slightly. I ordered two more clips from Gun Parts Corp and that should solve the problem. It jammed once or twice every third clip. Great shoooter and very accurate. I will also order a couple of packs of springs from Wolff like rick_reno suggested.

Thanks! Mike
