Garrison 45ACP Jamming

V

Vintage Vinny

Alpha
Just bought a used Garrison 45ACP PX9420S, went to the range and was very disappointed that it jammed 3 times within 100 rounds.
Any advice before I take it apart for cleaning and inspection?
Seems to jam on the 2nd round.
The gun only came with one mag, so I ordered two new ones from Springfield with 15% off coupon they sent me.

My guess is a magazine problem or ammo.

Give it a good cleaning/inspection.
Wait on your new mags.
Buy 2 different types of ammo.

Try new mag with old ammo, then try new mag with the 2 different types of ammo.

I have a 1911 that doesnt like Win White Bx, but runs great on other ammo
 
I would disassemble and clean thoroughly. Check the chamber for carbon buildup. Check the recoil spring for damage. Put a light ribbon of grease like TW25 on the rails of the slide and frame. Remove the baseplate, spring, and follower from the magazine. Check the magazine spring for condition and clean the follower. Pull a clean dry rag through the magazine body but do not put any lube in the magazine. Be sure your magazine is inserted fully. Now see if it runs.
 
The gun store said they cleaned it, but you didn't disassemble, inspect and lube yourself? That should be your normal routine on any new to you/used pistol. You familiarize yourself with the pistol. It's a bonding experience. You might be very satisfied what a thorough cleaning and lube can do to reliability. I use Enos Slide Guide in Lite viscosity on my Springfield pistols. It's light enough for cold winter months and summer months. Oil runs off to quickly.

I agree with magazines being a potential issue. The tubes may be filthy from prior use and/or the springs incorrectly installed (it happens!). I took six of my magazines apart yesterday, all were covered in junk. A thorough cleaning and the followers moved freely again. The 7rd SA magazines are good, but Wilson, McCormick or Mec-Gar are better. Hayes types faster. :LOL:

And try different ammo types. Some guns, especially 1911s, are particular about ammo.
 
If you have access to a skilled gunsmith get a throat & polish job done on it.

Contrary to popular belief "standard" factory guns don't get that extra TLC, and are just assembled.

Most factory guns run fine, but some don't and need some extra work done for reliable function.
 
As noted, clean and lube gun and clean magazine and try with other ammo. Next time out, take several pictures of the failure and note any peculiarities (e.g. extractor not in groove).
Do the normal things before spending money. I do see a lot of folks online who tinker and change things out without diagnosing the issues.
 
I don't doubt all the replies in this tread could possibly be the cause of failures to feed. Being as only one magazine was used the first place I would go is trying different mags. Of course a good cleaning and proper lubing should be done on a new gun as well as a used one before firing.
 
if after all those things are done and still an issue? contact Springfield, and ship it back. this very well may be the reason why the first owner dumped it.

which goes to another thread earlier about a gun malfunctioning......ship it to get fixed, when it returns sell it..don't sell a broken gun.

i have to wonder too, if the original owner of a broken gun can be sued? as there will be a record of who that was.

you know, for selling a known defective product, which could have (or did) cause a catastrophic disaster resulting in permanent injury or death.
 
Here is my two cents so take it for what it's worth.
Sorry about you issues.
I would give it a very thorough cleaning and I run my semi's wet, I use Lucas Oil Products.
Since you say it appears with the second round,could it be that you are anticipating the first shot and is limp wristing??
I don't know your ability and I am not suggesting anything, but these are just my thoughts.
 
With a QUALITY semi auto firearm, 90% of malfunctions are a result of bad ammo, a faulty magazine, poor maintenance, or shooter error. Eliminate those factors before blaming the gun. I cannot tell you how many times I have "fixed" malfunctioning guns with a simple cleaning and lube or change of ammo. Limp wristing can be an issue but less often with heavier guns like metal 1911's.

Another thing to consider, the higher the quality of gun, the closer the tolerances, and the closer the tolerances, the less tolerant the gun will be of sub-standard ammo.

O.P., That gun should run like a champ

Thank you all for responding. While I'm waiting for the new mags I'll clean and inspect the gun. Already bought better quality ammo.
