These guns tend to be very accurate with .40's and 10's and will handle most all commercial ammo. This is a medium frame gun and should be treated as such. Ammo which is loaded to maximum pressure levels should be used sparingly. Conversion can be done on fixed or adjustable sight guns. Barrel shortening is not available on fixed sight guns. 10mm Magnum is not a caliber option on the GP100.
Conversion to 10mm, .40, and .41 Special should be sent in immediately. Barrel will need to go out for rebore asap to shorten delivery time. Delivery time on all these conversions will run about 12 mos.
