Saturno,
I apologize if I was harsh. I get that way sometimes. Guess I've been at this too long.
If you want to PM me the specifics of your jams I'll be happy to make a suggestion or two.
Jams in autos come from very few sources. There are the ones that are inherent to the gun, but most (about 95 percent) are easily cured.
Think in terms of timing. The slide has so much time spent in recoil. The barrel drops out of battery for so long. After that the slide must pick up the next round, force it up the feed ramp and into the chamber.
A mag problem is indicated if the next round is stuck on the feed ramp or stuck pointing up at the top of the chamber.
If it is stuck on the feed ramp it is either a rough ramp that needs polishing or a mag issue.
If it is stuck pointing up at the top of the chamber it is probably mag lips that are too far apart.
Jamming on ejection is most likely timing. Sometimes a heavier mag spring will take care of it. It will slow down the slide during recoil.
If jamming on ejection is the problem then you must determine whether things are happening too quickly or too slowly and whether sufficient force is being delivered to seat the next round.
Here is where I would start: Brass should pile up about six feet from where I stand when firing. Farther away requires a weaker spring. Closer requires a stronger spring.
Once I have that adjustment taken care of I would consider my mag spring. If the failure occurs because the brass is caught in the action, I'd look to the mag spring. It is not pushing the next round up quickly enough to put it into proper position.
This goes back to the recoil spring. The Wolff tune-up kit is about $25. A lot less than a smith or even shipping to the maker.
There are only about a half-dozen causes for failure to feed or failure to extract. Once you have the specifics there are only two or three reasons issues will continue. Simple math means there may be about 18 issues to consider.
Start at the top of the list and you're down to about eight or 10 issues. Next step cuts it in half again. For the most part they are cheap and for the most part relatively easy.
Lastly, regardless of warranty, the first thing I do with any auto is polish the feed ramp and chamber. I do this routinely on new or used guns.
One of my biggest challenges was a Para I bought late last year and all it really took to make it 100 percent reliable was a spring set and a little ramp and chamber polish. It is now out getting custom work done.
If I may, don't look for a cheap way to achieve your goals, look for the right way - it wil be the cheap way anyway.
Again, I apologize if I went over the top. It just seems really simple to me and it always works.
In 50 years of fooling with autos, if polishing machine marks doesn't cure it - it's springs.
