Rob, gubb and Jason- thank you all for your contributions. I'm still very early in the learning curve of this pistol so the input is especially helpful to me.
@Rob, thought you had one, my mistake. Anyway, you are very experienced w/airguns in general so your input is appreciated.
@gubb36, the link on loading pellets in the mag will be a time saver. I fumbled around on the first few but got better after a while. But at first, I shot the two mags then resorted to the SS tray to avoid having to load the mags!
I may end up trying to fashion a carbine stock but not until I find a spare grip- I don't trust myself when it comes to woodworking. And I see now what you mean about the grip diameter, old vs. new. The old looks to be shorter but just as big OD.
@Jason- thanks for the tip on the hammer/valve O-rings. I'm all about good shot count, less ES w/o sacrificing too much MV, so that's perfect for me!
