RE: I picked up a Thompson .50 sidelock
I've got a tang peep sight for the T/C Hawkins and Renegade made by T/C. I will say it does make for some accurate shooting. The problem I have is when the afternoon sun sets in the thickets, and I want to stretch a few more minutes shivering in the tree.. it gets hard to get a clean sight picture in the shadows with the peep sight. I have since removed it and went back to a plain old iron sight and am just as happy.
I do like the looks of that RMC sight.
As for the hair trigger, what you need to do is practice with it. The more you try it, the easier it gets. Now on my rifles what I do when on STAND but never while walking or stalking, even with the hammer not cocked, you can engage the set trigger. When you cock the hammer, the rifle is a pre-sethair trigger. Try your rifle and see if it is not so.
If you have time on your shot, and want to cock the hammer without making a noise, pull the front trigger back. Now pull the hammer back as far as it will go. It will not have the two set stations where it cocks and makes a noise. Release the front trigger and slowly let the hammer come forward with your thumb still on it. It will catch in the cocked position and you have done all this with out alerting the deer. Now pull your set trigger and your ready to take your shot.
