Congratulations on your new Sig P320 and Canik TP9SFL and sounds like you've had a productive Range Trip!
Glad that the Sig P320 in .45 ACP is shooting fairly well!
Also glad that your Canik TP9SFL is accurate, and most all Caniks are, as even the lowest priced ones come with a Nitride finished Match Grade Barrel.
Sorry to read that you've had a feed reliability issue. Both my Canik made TriStar T120 and TP9V1 have NEVER failed to feed anything 9mm that I've fed it, so far.
My Canik TP9V1 also has a very very steep Feed Ramp, if you can call it that. I'm thinking it feeds more directly from the Magazine into the Chamber and bypasses the Feed Ramp.
I'm thinking you may have a Magazine Issue there. Give your Magazine a thorough cleaning and see if that helps.
Only a 10 round Magazine? My Canik TP9V1 Magazines hold 18 rounds. I can see where you would want a 10 round Magazine for shooting USPSA Production Class.
Glad that the Cz75 Compact is still delivering good times at the Range!
