If you send your gun to spears for releases and you want them put back to pull you will have to send it back to them.. Years ago you just had to remove a screw and take off the hook and it was back to pull . If i were doing one I would look for someone that made it easy to switch it back. A trapshooter never knows when he might get a crazy moment and trade..
I'll second having Phillip Crenwelge do the installation. Did one on my back up Browning combo about six year's ago and it's still going strong. He gets all my work. Check his schedule; he usually goes to the Spring Grand and you could get it done there. He is also the most reasonable on his price. Jerry Callaway
Spears did my Special Trap in 02. Dropped the gun off and as we pulled away my wife made the comment, "you'r leaving your gun here?".) Not much to look at and after we got the problems fixed the trigger has never failed me. Of course from time to time you have to clean it.
Oh, I forgot Phil did my 99, it has been great. He also put his hooks in my K32.
Gary Roman did my 3200 and it never really felt that good. But, it has worked well, after sending it back several times.
I have several 1100 done by Spears, Swab and unknown, they all work.
