I just recieved my T05 trigger mod up grade, and it took all of 5 minutes to install and adjust it, in my new RWS Model 54. I believe Chris is on to something here, unlike most metal triggers that have finger groves cut into the trigger blade his mod does not. This gives it a nice clean feel to the trigger when firing it, and lets your finger slide accross the blade at the same time. I am neither a fan of Plastic or Metal triggers, I just want something that feels good under my finger when shooting, add to that, that I have already upgradeed the power chamber, the RWS 54 is turning into on of the best guns of any kind I have ever fired. Add in Chris's trigger mod, I do not see how I can make this a better or smother shooter then she has already turned into. Just like a lovley lady, take care of her, give her what she wants and she will purr like a kitten with each and every round fired. Good Luck Chris, and thanks for the 1st rate and fast servie.
