Anyone think with a barrel change ,that the FNX 45 would become a good 10mm candiate ?
I have never carefully examined the breech face of an FNX45, but generally the issue with going from 45 to 10mm on the same slide is extraction.
I have to agree with sqlbullet, the width of the breech face is cut for the base of the 45 and the extractor hook becomes the issue. I don't know that much about the FNX if the barrels can swap to the other slides, the FNX40S&W barrel may not be dimensionally the same even where it sticks out the front of the slide. (Like with the Glock 21 and 30...)
The extraction rim of the 45 is thinner so you could see the thicker rim of the 10mm case not sliding up easily under the extractor. The good thing is the extractor is usually a cheaper replaceable part that can be reshaped & modified to accommodate the cartridge, only if it has enough reach for the smaller diameter of the 10mm.
Find someone that has the 40S&W and take some good notes and measurements.
sqlbullet , Thank you for your help . I didn't think about the extractor . I was thinking the ejection port was large enough .

Shadow , you make a lot of good points , and starting with the S& W 40 barrel , and slide makes a lot of sense . Thank you
But an FN made 10mm FNX???? How interesting. ...I would buy one or five!....anybody know anyone at FN can put in a word??
