I currently have a taurus PT111 thats about 7 yrs old and looking to get something a bit smaller, newer, more reliable, etc. I live in the south where its pretty hot all year so a bigger gun just wont work well with shorts. I am looking at the glock 43 and SW shield and open to others. Any thoughts? Both seem to have extended mag options available or coming. I am planning on shooting both soon as well. I dont carry with a round in chamber and am left handed so a safety is not an issue (i have kids tugging on me and stuff so I just cannot do it).
