I LEARNED SOMETHING NEW ABOUT HIGH STANDARD MODEL 107 THIS WEEK

[chief38]

About a week ago at the Range my friend was having major problems getting his 1970's vintage High Standard M107 to feed. It would fail to chamber almost every time and after a few magazines full, just gave up. When we got back to the house I noticed that the Chamber was filthy - looked like Lead but wasn't sure. We therefore did a thorough cleaning (probably the cleanest it's been since it was built) and we took it t o the Range the next day. This time, as the Magazine was being loaded the follower fell out of the Magazine as it had cracked in half where the hole is located. I helped him order a new one on line and after a week it showed up. I suspect that the two causes of the follower cracking are the gun only feeding the Cartridge in partially and the pressure on the follower was on an unnatural angle when the slide came forward and just fatigue of the old plastic part.

Anyway, I was confident that after the thorough cleaning, the replaced follower and a complete check, things would now run perfect again. The first Magazine was loaded with CCI standard velocity and the Pistol jammed on every single shot! We were both stunned to say the least!

Just for S&G's I pulled out an old box of Winchester Wildcats I had in my Range bag and we loaded the Magazine up. The Pistol ran perfect! Then I tried some CCI Mini-mags - and again the Pistol ran 100%. So we both examined all the different rounds and brands and what I came up with is that the CCI std. vel. are waxed coated. Sure as heck, the wax coating on the CCI's were causing the bullets to get hung up in the Chamber. The Mini-mags from CCI are Copper washed and fed perfectly as did the uncoated Wildcats. Well apparently he had just switched ammo and had never used the CCI std. vel. before and did not realize there was a difference.

So I learned something new yesterday - at least HIS particular HS M107 will not feed waxed bullets! I use the CCI std. vel. exclusively in all my .22 Rimfire pistols including my M41 and have no problems at all. So do others here who have High Standards have this issue or is he just an unlucky guy? I just can not believe the CCI won't work at all in a HS 107 (at least his copy that otherwise is prefect)!

What is Model 107?

What is Model 107?

I believe it is the Citation but I am not well versed in HS models.

Have to be careful with older lead .22LRs when used in an automatic pistol. The lead projectiles on older .22LRs oxidize and / or get crusty. You can still use them in a revolver but cannot use them in an automatic. Sometimes even difficult to get into a revolver chamber. I tried tumbling a handful of the older .22LR Target ammo but didn't seem to do too much to benefit. I have about 1000 rounds of RWS match ammo that is like this.

A standard reply from most all high standard people is to use S.V.ammunition .Some H.S.pistols develop frame cracks using High Velocity ammo .Most likely the mag lips need to be tuned ,as the H.S .do not have a feed ramp on the frame or barrel, rounds are fed directly from the magazine into the chamber.

High Standards are finicky feeders. Usually standard velocity CCI feed the best and are .02 longer than most other brands. Once you get magazines set up to feed the CCI then the other brands usually will feed well too. Your buddies gun seems to go against the norm. Most models do not have any feed ramp and the front of the magazine is the feed ramp. You can make adjustments by bending in or out the rear feed lips on the magazine to make it feed correctly- squeeze the lips inward to make it feed lower and outward to allow it feed higher. A tool is available that comes with specific directions to make your magazine feed perfectly then once set it will work well for a long time. The magazines most available and the cheapest are theTriple K brand but the lips on these are not as thick and sturdy as original factory magazines. You can tell an original by the 5 and 10 marks on side showing how many rounds are in magazine but fair warning original factory magazines are fetching between $50 and $150. The tool is not cheap either at around $30 on ebay. Good luck and enjoy.

I shoot CCI SV in my 107. Initially had issues with feeding high and used the magazine feed lip tool to readjust the rear lips. Magazines now feed fine.

You do need to keep the chamber clean but not having the issues you describe. Changing brands of ammo or changing lots may give you some fits as the rim thickness changes sometimes from brand - to - brand or sometime lot-to-lot.

For best results use the original Ct. mfg mags , Hamden ones are preferred . Later Tx. mfg ones can be made to work but take some fiddling to get right . Avoid the Triple K ones at all costs .

I have a as NIB Supermatic that will shoot a quarter at 25 yds using mini mags. Total Rd count 100 from new in 1956.

 

[flintsghost]

My pistols are all 101's and I haven't had any problems at all. I use all original mags however.

 

[Wee Hooker]

The high standards were always finiky with ammo in my experience. (Largely becuase they don't use a feed ramp.)
Back in my competing days, we used to put a drop of CLP on the top round of a loaded mag prior to use of CCI and Aguila ammo in HS and SW41's. This seemed to clean/lube the stack enough to get through the mag. The guns and mags did need more frequent cleaning when shooting waxy ammo too.

 

[Wyo]

I have a 103 Supermatic Citation, two Victors and two 103 Sport Kings. I use CCI SV almost exclusively in all of them and have had problems with none of them. High Standards can be finicky, though, and I would not want to speculate as to the cause of your friend’s problems. It could be any number of reasons.

 

[walter o]

my understanding is that triple K mags and H.S. are made by the same company .The difference is that the feed lips on H.S.mags are heat treated and keep their shape. As to shooting S.V. ammo in a high standard "It is your gun do as you please" but S.V.Ammo is more accurate and wont hurt the firearm. As recommended by others don't shoot super high velocity 357 in a model 19 and expect it to last.

Today my friend brought his pistol over and I dug out about a dozen different .22 LR configurations and brands. The ONLY ONE it would not chamber at all were the CCI standard velocity cartridges! Even the CCI Mini-mags (copper washed) work great! BTW I use CCI std. vel. almost exclusively (I don't own a HS though) and I find it to be the most reliable and most accurate of them all - especially in my M41. This HS pistol is 180º opposite!

What happens with the CCI is that the wax is just enough to keep the slide from chambering a round. It starts off just fine - then binds up half way into the Chamber. Even when the barrel is completely removed from the pistol, all other brands and configurations will drop fully into the chamber where as the CCI's will not. With ANY ammo other than the CCI std. vel. functioning is 100% so I have to surmise that this particular pistol just does not like the CCI waxed bullets.

Quite honestly, I was quite surprised as I have seen many other owners of High Standard Pistols use this exact CCI ammo with no issues. Hmmmmm - it's just the way it is!

 

[walter o]

when was the last time that the recoil (drive spring ) in the slide changed?

I honestly don't know - it's not my gun. Even if it was changed, the waxed CCI's still require way too much forward force to push in. You really need to push them in hard - not the way all the other non waxed ammo just drops in.
