That little window to test the pull is a terrific idea.
The local Cabela's has two racks of them, probably a dozen triggers total, and Saturday I tried four of them. They definitely varied in creep and overall feel. One was very good, two okay with a touch of take up but crisp letoff and one was as you stated, lots of creep and a lot of overtravel. They wanted list MSRP, $89.99 (actually four cents more than Ruger's MSRP) so I figured I'd look elsewhere. Sportsman's Warehouse only had two and for the same price, they were behind a counter so I didn't even try them. I spotted a couple on the internet for about $15 cheaper but with the variability in pull it's probably worth the extra money to try several in person and get the best one.
Just having trouble justifying the purchase of a $90 trigger for a rifle I originally bought for about $49.
