Yes it would be impossible to judge accurately, unless you were using ammo with an equal power factor.
It would be great to compare an XD, M&P, and a Grand Power side by side with the same ammo!
Sorry but I don't care for the Glock's
The Grand Power is now going to be imported by STI International and they have decided to import the updated version of the K100 called GP6.
I think there trying to duplicate the success that Springfield has gotton on there XD.
Has anyone in Europe or Canada shot a Grand Power K100 in IPSC? It will be newly imported to the USA later this year and I was wondering if it can compete with the likes of the M&P and the XD. I know the gun is already on the IPSC aproved list.
