I have a Walther CCP as my summer carry. Its a simple little single stack 9mm that still fits my hand profile better than the others I had considered. I like that they use a piston system and have a fixed barrel though its barely beyond 3''
I also have a Glock 19 GEN 4 in my bag tucked in a discrete portion. Others have commented on the backstraps and I'll be one to say that it was the difference maker in purchasing a blue label glock over a used XD .45 in the same price range.
In addition, I added a Hogue rubber grip around the glock which was a bitch to get on over the larger backstrap but it made a huge difference.
The first thing I did buying the glock was add tritium sights, I started with Trijicon who I love and got a good deal but there was a defect in the front sight. The ring was canted (fucking weird) so they swapped them out with Glock sponsored night sights (they have Ameriglo tubes) and honestly I couldn't be happier - especially when they refunded me the price difference.
Lastly, by my bed is none other than a Remington 870 tactical series. Its not Gucci'd out, just a shorter profile and an extended tube. I use the Aguila mini shells specifically (this is why I chose a pump action) and it holds 11 in the tube. Shooting it is a dream, almost no recoil whatsoever and great for follow-ons.
To anyone considering the KSG I would say go for it, it was wonderful and I had a primary arms red dot on mine. Incredibly small and maneuverable but I chose to sell and pickup the 870 for 300 and spent the rest on a pistol and strippers coincidentally.
SIDE NOTE:
Spartan Ranch isn't too far away from my location and they did great work for my gun toting roommate. I'm considering getting the Walther a nice polish and coat job, along with some trigger work and night sights as well.
On my buy list is a 300 blackout SBR in the 9'' range. Naturally I'll buy it as a pistol first and work to get the stamp done over the next 20 years or so. I'd like a 7.62 battle rifle but my mentioned homie has a house littered with guns to include a well kept FAL among others such as a lever action 45-70 with.... a red dot lol.
Life is good and preserved in our home. First line of defense is the Doberman/Rottweiler who, by all means, is probably a huge pussy if shit goes downhill. I love that dog though...
