I have a .22 tph. It is an interarms version. It doesn't seem to work too good. After I fire a round, the slide doesn't close all the way. The best ammo I have found so far are CCI minimags, which seem to work better than the rest. Any suggestions?
Thanks for the advice. I do notice that it seems to work better when it is clean and lubed, but after 50 rounds or so it starts 'acting up'. It has done this since I bought it new so I don't think the spring has worn out, unless it came that way from being stored for a while before I bought it. Where can I get a new spring?
I have heard that the interarms ones were not as good as the german ones and that is why they quit making them.
If that gun was sitting in storage for a few years it could very well have developed a "memory" in the spring. Meaning it started to take the form of it's compressed state. I had an underpowered (on purpose) 13lb. spring for a 1911 (factory is 18lb.) that did the same as yours. After a few years it felt pretty darned weak. I ordered a couple of new Wolf springs, again 13lb., and it felt twice as stiff and the gun worked great (patting self on the back since I built the gun). I think the first springs were from Bulleye.
You can try here but I would call them to make sure a TP will work with a TPH:
