I will echo what others are saying about staying with more mainstream brands. No idea about Tisas with regards to reliability but the other guns are ubiquitous and so shall be their support gear (holsters, sights, spare mags, etc.) I am not sure what you are looking to spend but a quick search showed $300-$400 range on your model. For that price you could get a CZ P-10, M&P Shield/Shield Plus/1.0/2.0, or police trade in Glock 26/19/17 all of which will serve you well with proven track records and more accessible gear. I would even look at the Smith and Wesson SD series if budget was under $300. There have been positive reports here with some users that have tested them out. Their new and improved SD 2.0 series has my eye.
