I'm considering adding a Jet Funnel to my USP 9 Expert and am wondering what advantages, beyond enclosing the higher capacity magazines, the jet funnel has.
How does the funnel affect the grip length and balance of the gun? I find the USP 9 to be just a tad short in the grip compared to my USP 45's, but I do like the slightly forward balance of the gun.
Are there any concerns with the translucent Jet Funnel magazines of recent manufacture? I've read threads reporting various issues when dropped on concrete or left loaded for long periods of time outside the gun--neither of which I intend to do (I shoot outside and this isn't a gun I'll be storing loaded magazines for)--but I have also read reports of weakened springs over time. Is it worth the cost-premium to go with the polymer-encased metal Jet Funnel magazines? I use my Expert primarily at the range for practice and the occasional IHMSA or Steel Challenge match. I have other USP's for other tasks such as field carry, home defense, concealed carry, etc. I don't need my Expert to be a handgun for all seasons.
Any other thoughts on the Jet Funnel? If you have added one to your Expert, how has it worked for you?
