I am intrigued by these guns and drawn to the relative low cost of having multiple calibers in the same weapon.
Specifically, I want to end up with a Witness Match in which I can shoot both .40 S&W and 10mm.
What is the best way to go? Should I buy a .40 gun along with a 10mm barrel, spring and mags, or a 10mm gun along with a .40 barrel, spring and mags? And why might one route be preferable to the other?
If I buy the 10mm gun, can I use its recoil spring with the .40 setup or do I still need a separate spring for the .40? (I know I can't do the same in reverse.)
Is the ejection port on the 10mm slide larger than the one on the 40 slide?
Will the 10mm mags really work without modification with .40 ammo?
I have never handled this weapon before but today did have a chance to handle and fire a CZ 75 Tactical Sport. I liked it but the grip frame is a bit too large in circumference for my hand and the safety slightly too much of a reach. From reading the specs of both weapons it appears the Witness has a grip that is somewhat smaller in circumference. Is this correct? Is the grip of the Witness a bit smaller than the CZ? And is the safety of the Witness a bit easier to reach?
I also plan to eventually buy an upper in .45 ACP but presume that intention will not effect the above choices. Please advise if that presumption is correct.
TIA
