oh i see .well in this case it's just better to buy one of each caliber.I will probably buy the .25 and go for the .22 once i've sold mine. I hoped it was just a barrel change and rotary magazine change.But if hammer spring is required also ... no thanks. Thanks again for everything guys , i'll post photos once i have it .Any other tips and tricks with this will be greatly appreciated.
I doubt there's any difference in the hammer spring between the .22 and .25
