Upgraded my Gamo Urban with a QuickShot trigger: I haven't dialed it in completely, it does seem smooth and light.
If I was to get a PCP I was definitely looking at the Gamo Urban... how is it on power with hunting pellets ? Accuracy ? That trigger looks nice..Quote from: Zsigmund on April 17, 2025, 10:46:44 AM Upgraded my Gamo Urban with a QuickShot trigger: I haven't dialed it in completely, it does seem smooth and light.
I put a quickshot trigger in the HW50S .22 today. The rifle has a Vortek PG4 Steel kit in it. I like the shape of the new trigger, and it's gold! Well not really... gold colored though.

First batch of .25 pellets are in the tumbler this morning. Reloaded the pot and it's coming back up to temp for round 2. Once that run is poured they will go in the tumbler and the batch in there will get sized and weighed while the pot comes up to temp again and batch 2 tumbles.The plan is to run 5 batches of around 125 each today. We'll see how that goes.

Hey Mike, I've probably got less than 250 shots through my Urban. I think it's a really good quality PCP especially for the Bargain Gate price I paid. Mine shoots CPHP 14.3gr pellets at right around 870 fps when it's topped off. At ten yards it can stack those same pellets in one hole. I've only shot out farther when plinking, about 25 yards, it hits easily for me at that range.
