Use the 'Winter gun, Summer gun' concept.
That is a larger gun for the months you can wear a coat, and smaller one for the hot summer months.
The 3 inch GP100 and 2 1/4 SP101 work well that way.
These are my two. GP100 Canadian Police and SP101 (DAO)
Nice thing is it is also the 'Always gun, House gun', and 'Main gun, Backup Gun'.
It can even the the 'His and Hers guns'!
Both can use the same ammo and both have the same manual of arms.
