I didn't list it in my previous post, but my .40's are comprised of a G27, 4013TSW, SW9940, 4040PD and a M&P 40C (original compact).
The 4013TSW was an impulse buy because I couldn't find one of the then-new aluminum compact 457 or 4513TSW's. I thought I'd take a chance on the compact .40 model I found. Some few years later I ended up being issued a newer version for work. I really like the 4013TSW with the wrap-around finger groove Hogue grip.
I got the SW9940 because it was similar to the guns my agency was trying out.
The G27 wasn't a planned purchase, but just came my way for a price too good to pass up. It had been a factory demo gun for a gun writer, equipped with NS, and had been NIB before having been used for the article.
The 4040PD was a whim buy of a lightly used 1-time T&E gun.
The M&P 40C was my second M&P, and at the last minute I decided to order a compact .40, instead of a compact .45. It shoots like a full-size .40 and feels fine in the hand during live-fire, but I've toyed with the thought of trading it for a Shield 40. I simply prefer the 4013TSW and 4040PD to the 40C, and I'd not mind having a thinner and slightly smaller .40 in the stable.
I had the opportunity to buy a 1-time T&E 4003TSW or 4006TSW for less than $700, and while I thought about the 4003TSW, it was just too large for my EDC preference. The 4006TSW was both too large and too heavy (which is why I never had one issued to myself for work, and why I got rid of the issued 4566TSW after only carrying one for several months

).
I find the chunky G27 'good enough', having put more than 15K rounds through it over time, but really prefer the 4013TSW or 4040PD for the grip ergonomics and triggers.
If I had to do it over again, I'd probably keep the 4013TSW and add a Shield 40. Well, I'd also probably keep the G27, since it's a decent 'beater' EDC. As much as I've gotten a lot of use out of the SW9940 and 4040PD over the years, I have no need for a full-size .40 nowadays, and I still prefer my 3913 & 3913TSW to my 4040PD, all things considered.
