Hello Everyone,
I wanted to document and share modifications I performed on a Jiminez JA-22 autoloading handgun to significantly increase its reliability.
***Every firearm is different. The modifications I performed resolved issues with only this firearm. I do not recommend anybody perform any modifications to any firearm. These modifications will void factory warranties, please refer to your firearm's manufacturer for additional information.***
Before modifying, this handgun would consistently FTE and FTF regardless of ammunition type and style of projectile (CCI, Aguila, Remington and Federal where primarily used). At one point it found a "happy place" with Remington Thunderbolts but after cleaning the firearm I could not recreate the positive reliability of that shooting session.
The images attached to this post contain images/details to what was done. After performing these modifications the firearm will now reliably perform at a near 100%. I say a near 100% because after about 250 rounds of mixed bulk ammunition and bullet types, switching to higher QA'd CCI ammunition will allow the firearm to continue firing reliably without flaw. I've yet to have the firearm malfunction using CCI ammunition after making these modifications.
I don't recommend anybody perform these modifications to their firearm, if you have a Jiminez JA-22 that experiences FTE's and FTF's I hope this information can assist you with determining what components may be causing problem(s).
