x2 agree with targettarget
have various 9mm, glocks, beretta, hp, sig, etc., and 1911's
do try diff models out if you can, after the fact, you would not think anymore about whether you spent an extra couple hundred dollars more for a model that you find fits you and your shooting style best
as said on other posts, i think the 345 is of great value, what you get for the price, and it is very underrated as not being a high seller, while gun reviews about it are great.
there is nothing more for you to add to the gun, it works as is, decent sights, trigger, reliable, nothing to improve and there is zilch for after market parts anyway, except you need extra mags, and likely you need the store to order you extra, as no used mags out there that i have ever seen, gun comes only with 2 mags, and you should get more, i think 5 mags per semi auto is the minimal/optimum number and you need to factor in the cost of extra 3 mags, whatever the price is
now if you go with a 1911, chance are you can get extra mags cheaper than 345 mags possibly, so decision is whether you end up spending more $ on the gun, or more $ for extra mags
i have owned both the standard version and the decocker model, if you go with the 345, suggest the decocker version to buy, planning to buy a decocker model again in the future
the standard model has the slide safety, but this is redundant as it is a double action first shot anyway, the decocker version is faster, imho, working like a sig to take the gun from sa mode back to da mode, with a spring mechanism, no locking safety needed
9mm ammo is cheaper than 45. with 45 acp, it is best to reload and that is a hobby in itself, or if you have a friend already reloading, this would be the best, either learning from the friend or have he (or she) do the reloading for you, at cost and favours in return
good luck, part of the fun is in the shopping!!!
