I just got a new .25 M3 a couple weeks ago, after tuning, it shoots very well with JSB MK 2's....I love it, but the cocking handle felt too small to me. The other day I machined a larger cocking handle and knurled it. I tried it out yesterday and to me, it made a big difference, I really love it now, it's amazing what some small changes can make....I blacked it out and re-installed it today....
