Good choice. I have a silver 43x and a silver and black 48. I use the Shield 15 mags and metal mag release in the 43x. Use the Glock 10 rounders in my 48’s. On the range the 48 is easier to shoot than the 43x. The extra barrel length makes a difference. I have an IWB holster that will carry the 43x and 48. I cannot tell any weight or size difference I can notice when carrying either one. Both guns are keepers!
