Why is it that my Gen 4 G26 RSA occassionally pops out of its seat to the point that I can't get the slide off? It is normal for the RSA to become unseated to a certain degree; however, mine comes out completely on occassion and gets stuck in the serial number cut out. This is happenning when I go to field strip the gun after I am simply dry firing without a magazine in the gun and obviously no ammo in the chamber. I have a Gen 3 G26 and G27 and they have never exhibited this issue. In the meantime, I ordered and recieved a new spring (older version) from Lone Wolf and it also occassionally pops out of its seat to the point that I can't get the slide off. Any ideas as to what could be the cause of the spring popping completely out of the seat and getting stuck in serial number cut out? In the meantime, I am going back to work on getting the slide off. I am having more difficulty doing so this time the the previous times.
