I use a G19 now but I would like to get a G34 or 35 to do some competition type shooting at my club. Steel or USPSA at some point but right now there is nothing close by. Until then I can have fun and practice with others at my club. I would love to do some GSSF competitions but there are none near me this year, maybe next year. I was first thinking I would go with a 34 but before I place an order and wait months for delivery, I was wondering if it would be a better idea to get a 35 and have the ability to set it up for 9mm as well. Whats the drawbacks?
