Well buddy the tune's that I did on my B3's made a world of difference since the B's are known for their rough.....everything. Afterward's they were like a different airgun, from the trigger pull to the smooth cocking and feel of the B3 when I shoot them. everything on the B3 was gone through, trigger foward. Now my 2240 I went to work on the trigger, polish, lighter spring, custom spring guide and custom trigger shoe which all add's up to a very smooth and light trigger pull. Also made a brass safety switch for it and got rid of that plastic one. But most important to me was learning to HOLD and SHOOT airgun's . Understanding your abilities and the airgun's go's along way when giving your babies a tune and some mod's. Ed
