Default Holosun 507C or 507K for 5" pistols

Hey guys, I have a PPQ Q5 Match and a VP9L optics ready.
I keep changing my mind over and over and back again whether to put Holosun 507c or 507k on both of them.
507K seems to be designed for smaller framed pistols and im wondering if it will be a little TOO small for these large frame 5" pistols.
However when I look up pics of 507C on a Q5 or VP9L they look HUGE to me.
I havent held either one in my hands so I have absolutely no clue as to the actual size of the optics.
Obviously the bigger the window the better but at the same time I dont want it to look like I got a 510c on a pistol.
And on the other hand I dont want a tiny little window either.
I am literally 50/50 on C or K.
Can anyone with experience guide me towards the right red dot sight for these 5" pistols?
We just use the pistols for some fun shooting, and I every now and then will use the VP9L for IDPA competition

Thanks in advance

I’m extremely happy with my green 507c on my 19mos as well. I honestly prefer it to my RMR. I would go for the green dot IMHO.

507c is for full sized pistols using the RMR style footprint.

507k is designed for the micro pistols and it's of the Shield RMS style footprint so your pistol isn't probably cut for this style footprint.

TLR go with the 507C.
