IZH 46M help

[larspawn]

Been out of the game for a while.  But hoping to get some advice here on a IZH 46M.

Don't know what happened but lost the transfer port seal.  I had a spare but the issue is after installing it, I cannot get the transfer port to latch down to the barrel.  I am pressing way harder than I used to before.  Actually, a simple click but now pressing hard it won't catch.  Any suggestions?

Please disregard. I fixed it. 

I haven't been shooting much since my vision changed.  I find that I just can't see worth a dime with these Progressive lenses.  Well seems I put the seal in upside down which didn't leave enough space for lockup.  Problem fixed. Geez getting old really not worthy!
