First, let me get this out of the way, I know that this lower does not have last round bolt hold open. I'm talking about manual engagement of the bolt catch.
I have a newly assembled 9mm carbine, PSA PA-X9 Lower with PSA Hybrid Upper. Shoots great with no malfunctions of any kind in the first 150 rounds of cheap 115gr FMJ that I put through it. However, it does have an issue that I've not seen before and that I'm not sure how to address. With bolt held back by the charging handle, and the bolt catch manually engaged, riding the bolt forward until it contacts the catch does stop bolt. But, as soon as I remove my thumb from the catch the bolt face slips off of the catch and goes home. Just to make sure that the catch from the PSA LPK wasn't undersized, I swapped it out for a Seekins Precision Encanced Bolt Catch with the exact same result. Looking at it closely, it appears that the lower part of the bolt face is narrowed so much to feed the single stack Glock mags that it doesn't offer enough surface are to hold onto the catch.
I'm looking for advise from others who have had this problem or feedback from folks that have this combo from PSA and don't have this issue.
I did email PSA on the 4th, and again today, but have not gotten a response.
