Sounds like a good reason to buy another gun!!
These folks have Glock 17 police trades for $389.00
I know from your other thread you want something to practice with but 10mm is very expensive. A G17 would have a similar feel and trigger to your G20 just not as big a grip. The only other solution is a 40 S&W barrel for your G20 but being in Alaska 40 S&W might not be much cheaper than 10MM.
