Upgrading / Replacing Parts in an M870?

[paradoxum]

I've got this Golden Eagle M870 Tri/Six shot Shotgun: https://airsoft.tiger111hk.com/p38566/Golden-Eagle-Sawed-Off-M870-Gas-Pump-Action-Shotgun-(Real-Wood)/product_info.html

 

There's nothing wrong with it, works fine, but I've a habit of just wanting to replace parts in my guns.. for.. reasons.

I've found these parts:

Angel Custom CNC Steel Ball Bearing Spring Guide w/ 130% and M120 Springs for Spring Powered Tri-Shot Airsoft Shotguns

Angel Custom CNC Steel Nozzle Latch for Spring Powered Tri-Shot Airsoft Shotguns

Angel Custom Steel Trigger Latch for Spring Powered Tri-Shot Airsoft Shotguns

among others.

I've not taken this gun apart so I don't know the quality of the stock latches etc, but does anyone know if that higher tensile spring is compatible? and mostly when it comes to replacing the other parts I'm thinking about long-term durability, would those angel custom ones last longer etc? has anyone done anything like this with a similar gun? 

Thanks in advance.

All those parts are for spring shotguns...

Just leave it alone and it will be fine. They really just dont need anything doing to them.
