One of my favorite pass times is plinking at cans and the occasional chipmunk while sitting on my deck in Michigan. I use a Gamo .177 pellet gun. This is a powerful single pump rifle that is surprisingly accurate. I purchased it at Wally world about 7 years ago and it has never failed. A couple of months ago I decided to do something about the long, hard, notchy trigger pull. I found this site CharlieDaTuna offers NPSS, NP, CBR, GTX-III, GRT-III, GRT-4G triggers and decided to give it a try. Only $33, but the seller prefers to deal in cash only. Well, he is honest! I received my trigger a week later and installed it according to the instructions on the website. Took all of 15 minutes! What a remarkable difference! I have several friends with similar air rifles and they are asking that I upgrade theirs as well! This trigger transformed a fun plinker into a very accurate, easy, smooth, deadly (for chipmunks!) gun. Now if summer would just return, I would love to head out on the deck with a cup of coffee and a "tin" of pellets for a couple of hours.
